When I refer to a "pasture trim" I am not meaning some half assed trimming job.
I am not arguing that some farriers are making a killing doing a crappy job and calling it that. But for us it is important that it is done right. In the winter when we pull the shoes off of the ranch horses we put a "pasture trim" on them. We still use them through the winter so its important that it's done right otherwise in the packed snow and ice there won't be much hoof left. No different than riding through the rock piles.
Some cowboys I know buy the Borium and make their own ice shoes or put in frost nails. This can be spendy. But if, what I call, a "pasture trim" is done correctly, it's great and I don't have to spend 20 minutes every morning chipping ice out of shoes.
Also if I find after pulling shoes a horse is sore I am not scared to put a little Venice Turpintine on his soles for a couple of days. If he don't improve then the shoes go back on. I am not going to make one tough it out for too long.
